A masterplan for an Islamic hub at an existing school has drawn ire from some residents for its "exclusivity" and being an inappropriate use for the site.

The Australian International Islamic College (AIIC) at Durack, in Brisbane's southwest, has submitted a development application that would expand its K-12 college, and add a mosque, childcare centre, medical centre, aged care accommodation, shops and apartments.

The Australian International Islamic College's project manager for the development is receiving treatment and unavailable to comment on the plans.
